Setup Instructions
Follow these steps to set up your charger:
- Unpack: Carefully remove the charger from its packaging and inspect for any damage.
- Placement: Place the charger on a stable, dry, and well-ventilated surface, away from direct sunlight or heat sources.
- OBC Bypass (if applicable): If your Club Car's Onboard Computer (OBC) is suspected to be faulty, use the provided OBC bypass cable to connect directly to the battery terminals. Otherwise, proceed with standard connection.
- Connect to Golf Cart: Ensure the golf cart is turned off. Connect the charger's DC output plug (Club Car style) securely into the golf cart's charging receptacle.
- Connect to Power: Plug the charger's AC power cord into a standard 110V AC electrical outlet.

Operating Instructions
Once connected, the charger will automatically begin the charging process.
- Initiate Charging: After connecting the charger to the golf cart and then to the AC power outlet, the charger will automatically detect the battery and begin charging.
- Indicator Lights: Observe the indicator lights on the charger. Typically, a red light indicates charging in progress, and a green light indicates a full charge or trickle charge mode. (Note: Refer to the specific LED indicators on your unit for exact meanings.)
- Charging Time: A full charge typically takes 4-6 hours, depending on the battery's discharge level.
- Trickle Mode: Once the battery is nearly full, the charger will automatically switch to trickle charge mode to prevent overcharging and maintain battery health.
- Completion: When the battery is fully charged, the charger will automatically shut down. Disconnect the AC power cord first, then disconnect the DC output plug from the golf cart.

Troubleshooting
Refer to this section for solutions to common issues.
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on / No indicator lights | No AC power; Faulty outlet; Damaged power cord; Charger malfunction. | Check AC power connection. Test outlet with another device. Inspect power cord for damage. Contact support if issues persist. |
| Charger shows red light but does not turn green (fully charged) | Battery deeply discharged; Battery fault; Charger fault; OBC issue (if not bypassed). | Allow more time for charging. Check battery condition. Ensure OBC bypass is correctly implemented if needed. If the charger runs for an unusually long time without switching to green, disconnect and contact support. |
| Charger automatically stops working | Safety protection activated (overvoltage, overcurrent, overheating, short-circuit, reverse-connection, no-load). | Check for short circuits or incorrect connections. Ensure proper ventilation. Allow charger to cool down if overheated. The charger should resume work automatically once the fault is cleared. |
| Charger does not shut off after battery is full (potential overcharging) | Charger malfunction; Battery fault. | Immediately disconnect the charger. This indicates a potential fault in the charger's automatic shut-off mechanism. Contact customer support for assistance. Continued use may damage batteries. |
